Here are links to two PDFs. The first seems useful for developing large structures or cores (albeit traditional ones) around which long narratives can be built. The second gives simple, direct steps (scaleable steps, good for scenes or books) for building narratives.
The first is from Now Write!: Fiction Writing Exercises from Today’s Best Writers and Teachers. The second is from The Lie That Tells a Truth: A Guide to Writing Fiction.
Enjoy.
