Try to understand the scenario if any.
Try to think as an auditor and start from the basics.
Learn 3 to 4 common procedures which are applicable almost in every situation and link your procedures from the scenario.
In addition to what Mohammad Said, use your common sense when conducting a test on assertions for example, if asked to perform procedures on Account receivable then you may think of 1) comparing this year to last year 2) obtaining list of outstanding sales invoices and tracing them to sales ledger and nominal ledger and further to the SOFP to ensure completness and so and so
So the best thing is to put on the shoes of the auditor and think a while like him or her.
