I am by no means an expert, but here is what popped into my head first when I read your post. Hope some of this helps!
Waldorf Without Walls has a book, Waldorf Reading for Homeschoolers. On that site there's also this short article, Waldorf and Learning to Read.
The Christopherus site has some samples from Living Language if you scroll to the bottom. Keep in mind that they're just samples and might not have much useful info to start out with.
There's a Green Meadow Waldorf School video too (How Reading is Taught in a Waldorf School) that is a pretty good starter. If you like videos, you can Google it ("reading Waldorf")!
**ETA** Forgot I had seen this one from Parenting Passageway.
