Any Advice?

I've been tutoring students by using Orton Gillingham method for almost a year. Unfortunately, I run into snags here and there. For example, one of my students is having a difficult time with decoding two-syllable words. I'm still in the early stages of teaching him but sometimes it seems as if he remembers certain similiar words and tries to say what he remembers and not exactly what's in front of him. And when I work on reading comprehension, a few of my students struggle with sequencing of events, remembering what happened and vocabulary. It is a very difficult process but does anyone have any suggestions?
