How about a special edition of one of Lewis' books, such as "The Lion, the Witch and the Wardrobe"? You could also get him a set of all the books in the Chronicles of Narnia series. Another idea would be to get tickets to a local theater production of "The Lion, the Witch and the Wardrobe" or a movie adaptation of one of Lewis' other books, like "The Screwtape Letters." Additionally, you could create a gift basket filled with items that represent his love for Lewis and his works, such as a bookmark, a quote from Lewis framed nicely, a tea cup with a tea blend that he might enjoy and a leather journal to write in.
Or you can get him a star map with the date when he was born.
