Jonathan,
There is much more than just the promotion of magic in his stories. The trouble is, there are many stories, including 7 books and several hundred pages in his Narnia series alone. It would require a massive expenditure of time and energy to attempt to decipher and organize a refutation of everything hidden and contained in his books.
Starting with his first book, the Lion, the Witch and the Wardrobe, allow me, if you please, to point out just a few things.
Lucy is portrayed as a very naive and innocent little girl, the youngest of the four children. She enters Narnia (Babylon) through the "secret chambers," i.e. the wardrobe. How do we know Narnia is Babylon? In several ways, but to begin with, what are the creatures that she encounters there? The very first creature she encounters is a monstrous creature named Mr. Tumnus, who identifies himself as a faun.
The book of Isaiah is part of our Lenten readings and soon we will come to chapters 13 and 34, in which fauns, which are also called satyrs, and incubi, are shown to be inhabitants of Babylon.
St. Augustine - The City of God
"There is, too, a very general rumor, which many have verified by their own experience, or which trustworthy persons who have heard the experience of others corroborate, that sylvans and fauns, who are commonly called "incubi," had often made wicked assaults upon women, and satisfied their lust upon them..."
Now, we have to ask ourselves, why would this supposed Christian C.S. Lewis invent a story where one of the main characters is a monstrous two-horned faun, which befriends a naive little girl and lures her back to his cave dwelling? Then he plays a lullaby on his pan pipes, and she falls asleep for seemingly hours.
And the tune he played made Lucy want to cry and laugh and dance and go to sleep all at the same time. It must have been hours later when she shook herself and said...
What kind of wicked assault made this Pan-like faun on young Lucy as she was asleep for hours? Did he satisfy his lust upon her?
Would you believe that I'm the sort of Faun to meet a poor innocent child in the wood, one that had never done me any harm, and pretend to be friendly with it, and invite it home to my cave, all for the sake of lulling it asleep and then handing it over to the White Witch?"
I won't elaborate in graphic detail of the meaning behind the euphemism of being handed over to the white witch. Suffice it to say, that in this story, on the surface, it all seems to work out well in the end, for the faun actually ends up becoming great friends with young Lucy and not turning her over.
So what is the lesson that C.S. Lewis teaches young girls who read his stories, and admire and want to emulate Lucy the Valiant, Queen of Narnia? That it is perfectly safe and acceptable to be lured back to some strange man's (or beast's) home by the temptation of sweet cakes and sardines. Even though you were somehow magically intoxicated and asleep for hours, that nice little faun wouldn't dream of making a wicked assault on you, as was explained in the fathers, right?
The same notion is repeated with the next youngest, Edmund. He is seduced by a much older "woman" with some warm drink and Turkish delight. Lesson for the children: don't be afraid of strangers in strange places, who seduce you with treats. It will all work out in the end, and nothing bad will happen to you in the company of these devilish creatures.
So the children sat on their thrones and sceptres were put into their hands and they gave rewards and honours to all their friends, to Tumnus the Faun, and to the Beavers, and Giant Rumblebuffin, to the leopards, and the good centaurs, and the good dwarfs, and to the lion. And that night there was a great feast in Cair Paravel, and revelry and dancing, and gold flashed and wine flowed, and answering to the music inside, but stranger, sweeter, and more piercing, came the music of the sea people.
How interesting that these children are introduced to dancing of satyrs, Bacchanalian revelries and wine. Lucy and Edmund seem a bit young to be partaking of a pagan wine festival, no?
Dialogue of Palladius Concerning the Life of St. John Chrysostom:
[A] man who (so I have often been told) carried theatre girls upon his shoulders at drinking parties lit for satyrs, his head garlanded with ivy, and a bowl clasped in his hand, playing the role of Dionysus in the fable, as master of libations
St. Jerome Letter to Marcella:
Have I ever embellished my dinner plates with engravings of idols? Have I ever, at a Christian banquet, set before the eyes of virgins the polluting spectacle of Satyrs embracing bacchanals?
St. Clement of Alexandria - Exhortation to the Heathen
"Stop, O Homer, the song! It is not beautiful; it teaches adultery, and we are prohibited from polluting our ears with hearing about adultery for we are they who bear about with us, in this living and moving image of our human nature, the likeness of God,--a likeness which dwells with us, takes counsel with us, associates with us, is a guest with us, feels with us, feels for us...
Such are examples of your voluptuousness, such are the theologies of vice, such are the instructions of your gods, who commit fornication along with you; for what one wishes, that he thinks, according to the Athenian orator. And of what kind, on the other hand, are your other images? Diminutive Pans, and naked girls, and drunken Satyrs, and phallic tokens, painted naked in pictures disgraceful for filthiness."
Eusebius of Caesaria - Preparation for the Gospel:
(quoting Diodorus)
"'The priests who succeed to the hereditary priesthoods in Egypt are initiated in the mysteries of this deity: the Pans also and the Satyrs, they say, are honoured among men for the same reason; and therefore most persons dedicate images of them in the temples very similar to a he-goat; for this animal is traditionally said to be extremely lustful."
St. Jerome
"Antony was amazed. and thinking over what he had seen went on his way. Before long in a small rocky valley shut in on all sides he sees a mannikin with hooked snout, horned forehead, and extremities like goats' feet. When he saw this, Antony like a good soldier seized the shield of faith and the helmet of hope: the creature none the less began to offer to him the fruit of the palm-trees to support him on his journey and as it were pledges of peace. Antony perceiving this stopped and asked who he was. The answer he received from him was this: "I am a mortal being and one of those inhabitants of the desert whom the Gentiles deluded by various forms of error worship under the names of Fauns, Satyrs, and Incubi."

http://www.theoi.com/Georgikos/Pan.html
PAN was the god of shepherds and flocks, of mountain wilds, hunting and rustic music. He wandered the hills and mountains of Arkadia playing his pan-pipes and chasing Nymphs. His unseen presence aroused feelings of panic in men passing through the remote, lonely places of the wilds.
The god was a lover of nymphs, who commonly fled from his advances. Syrinx ran and was transformed into a clump of reeds, out of which the god crafted his famous pan-pipes.
Pan was depicted as a man with the horns, legs and tail of a goat, and with thick beard, snub nose and pointed ears. He was often appears in the retinue of Dionysos alongside the other rustic gods.
