There's a video out there of Martha King doing an IFR checkride that's pretty good.
My oral pretty much covered just about every preflight planning item in depth: Weather (interpretation, when wouldn't I fly, etc...), Route Planning (how was I going to get from entroute to the IAF, do I need an alternate? had I needed an alternate how would I select it, what would I do if we lost comms ), My readiness (currency, BFR,etc...), Airplane readiness (inspections, certificates, etc..>). During the preflight there were some questions about the aircraft systems.
Once we fired up, it was a straight forward run of the IFR tasks in the book. The only real technical question at that point was during the partial panel approach, he asked about the interaction between the vacuum system and my autopilot. I told him the autopilot wasn't affected at all (and in fact, neither was the HSI he had covered up with the nopeekies). He suggested I fly the approach with the autopilot then, which I did for a few minutes but it was gusty enough he suggested I could do a better job hand flying.
The departure airport had a hold in the ODP, so we got the hold out of the way there. I used the AP to fly the hold so I could reconfigure to enroute from takeoff.
