I agree pre-printed questions are not good. Also if you are auditing to TS2 they are not acceptable as audit documentation by your 3rd party auditor.
First, you should understand the process. This can be done by walking through the process using the "process definition" as a guide. Once you understand the process then you can ask questions. Your questions should be based on inputs, activities, outputs, linkages(from & to), support processes and previous audit results.
