Audit Guidance Request

I transferred from Operations to Compliance (as an Auditor) in March of 2004. My predecessor was not able to leave me complete instructions for all the different audits I’m expected to conduct. I’ve used both Kirchman’s and the FDIC audit procedures/guidelines. I’m sure there are other sources for step-by-step procedures to complete an audit, but I’m unsure where to look for them and/or what might be considered reliable? Please advise.
