In a serie of blog post, Guy Kawasaki gives template documents for financial forecast, business model and pitching.

To start with, the financial document reconcile vision and details. On one hand the document  support the vision with a non detailed 5 years forecasts. The goal is to check the basic assumptions behind the model. On the other hand, one sheet is dedicated to the next year forecasts in much more details.

Then comes the pitch.

 The business plan will be a full text version of the pitch.

In my opinion, this last document, unless you want to raise, can be replaced by more agile methods.

The book running lean for instance propose a methodology to iterate very quickly between business model hypothesis for web based ventures.
