There is a book called "100 Easy Lessons" that you can find in most bookstores. It is a sort of mini-Direct Instruction course intended for parents to deliver. It isn't an intensive enough resource if you're really looking at dyslexia, but it is an easy, systematic, 10 minute per day approach to teaching decoding skills. I've been very impressed with outcomes I've had using Direct Instruction techniques and materials as reading intervention for students with decoding and fluency difficulties. It might be worth a try before committing to a more expensive and intensive approach.
