My advice, think about all the little things that you haven't thought about since your first time in the aircraft. Dumb it down and list ever step in doing something. You'd be amazed at how automatic something like turns about a point will be for you do do, but think about the fact that the student sitting next to you hasn't done it, and has no idea of what or why you're doing it. What are you looking at? When are you looking at it? What are you doing to the controls? Why are you doing it? You get the idea.
