There are several great printable templates available for planning your website design. Here are the ones I found most useful.

I recommend learning about the Visual Vocabulary from Jesse James Garrett. The website has detailed information on how to describe information architecture and interaction design. (The book is also a good read.)

Zurb has a set of responsive sketch sheets and a good article on using them when planning your responsive design.

Inspiration Hut also has a set of printable papers.
