One popular method for organizing a non-fiction book is to create a "101 Ways To..." collection.
Simply create a laundry list of methods to do something within your topic. Then, write 2 pages of content for each of the items on the list. When you've finished the writing you'll have a 202 page draft of your book.
A quick
search of Amazon.com using the phrase "101 Ways To" yielded 3,398 books, so you can see that it's a popular approach in the marketplace.
