Here's a blog post which points to a New Scientist article on a paper
which postulates that a collision of two proto-planets might be
responsible for the formation of Venus and explains its lack of water
and funky rotation. The article is subscription only, the blog post is
light on details, and the paper itself they are both based upon is
also subscription only but hey, it's a start.

If Venus underwent such a massive collision, where is the debris? Venus should have one or more moons accreted from the debris.

Or part of the debris escaped and part recoalseced back into the proto-Venus (possibly with a brief ring phase first). Not all collisions result in independent satellites; after all, that's not how we think most planetary satellites got made.
