The most basic QA process is a checklist, and that might be a good place to start. In monitoring development of testing scripts, for example, I've often come up with a template and a checklist. The template gives someone quidance and a format and expectations; I use the checklist to look for specifics and for the main characteristics or items that should be included in each section of the document. The checklist may grow as I discover what works and what does not.

Both these basically take the desired standards, or requirements, and then develop categories of what to review in them with a few guiding questions under each. You should also define your process -- who will do it, how they will do it, how they will present their findings, how revisions will be handled. This could be a fairly simple outline or checklist (1-2 pages).
This one (http://obswww.unige.ch/Instruments/GIRAFFE/Files/VLTdoc/pdf/docReview_ins1.0.pdf) includes a flowchart of the process they used -- a visual like that can make it easier to walk through. Note that it also provides a format for the reviewer, which will guide what kind of things the review needs to look at and evaluate.
Hope these examples are useful. The principle of defining your 'requirement' and then testing that requirement apply easily here. Define an outline or template or existing standard to use, and then develop a checklist to mirror it, and describe the process (and roles) for how the review will be done.
