I see those patterns at the Houston Quilt show. If you look at a quilted jacket, most of them are very simple. They are very like a top shirt, but most likely with a zipper front and all finished seams on the inside. You won't need facings. You can adapt a pattern with few pieces to use the pre-quilted fabric. Look at any of the pattern manufacturer...McCall or Simplicity. There are more, but I can't remember their names right now.
This page may have something you would like. I see several cute ones.
