As a substitute teacher I always appreciated well formatted, easy to read sub plans. As a teacher, I hated writing those plans. None of the templates I downloaded seemed to work for me so I created my own!
This template includes a quick cover page with a spot for an introduction and highlights any students that have medical, academic, or other needs (great reference for a sub). It also includes schedule blocks where you can type in your own plans for each subject (subject headings are included at the end so you can move them where you need them!) and a roster page where you can insert student photos and names (helps the sub identify students by name or leave a specific note if necessary).
