Here are some templates for wireframing, using Sketch & Adobe Indesign. Sketch has dominated the market as the industry choice for digital design. If you have a Mac, I encourage you to use Sektch. If not, another good choice is Adobe InDesign (PC and Mac). Depite being originally intended for print, InDesign is a very flexible tool, which integrates well with Illustrator and Photoshop, and is great for managing and outputting sketches for review.
