Help! How to create a UI Tech Spec [closed]

Crap. I've been tasked to create a technical spec for a UI I am developing. This is my first real developer job, and after looking at the tech spec for the backend of the project, I feel a little in over my head. I can do mockups and wireframes till the cows come home, but I'm not really sure how to put all this information together.

Does anyone know of a good resource or possibly a good example of a UI tech spec?

What is a UI specification document?

A user interface specification (UI specification) is a document that captures the details of the software user interface into a written document. The specification covers all possible actions that an end user may perform and all visual, auditory and other interaction elements.

Not sure if this is any help, but I like how the mozilla project is detailing ui specs on their wiki.
