As a new instructor I was so overwhelmed. It seemed like everything was coming at me so fast. Though I know the material I was about to start teaching I felt the hardest part was preparation for classes. Thankfully, the previous instructor left all the previous material (PowerPoint, handouts, test, etc) that I used as an outline. I did not try to "reinvent the wheel" and it was of tremendous help. I cant even imagine how much more overwhelmed I would have been if I had to start from scratch. My advise to all new instructors, at least for the first couple of terms, use the same outline as what was used before. In time, you will know what works and what doesn't, and slowly but surely you will eventually modify the course to one that fits you.
