You'll get a lot of different answers. For myself (stock -10, except for having balanced the fuel injector nozzles, stock 60 gal fuel tanks):
Takeoff 2700 rpm, full throttle.
Soon after breaking ground - rpm to 2600 (LVK is noise-sensitive)
Passing thru 1000' AGL - MP to 25", rpm to 2500, mixture leaned for FF around 15 - 17 gal/hr (higher outside temp, higher FF, to keep CHT's in line), airspeed 120kias (unless there are obstacles). I have been using flaps full up but may start using flaps in trail, after reading commentary from Vans. Obviously passing thru 5000' or so it's whatever MP I can get with full throttle.
Cruise - if I'm in a hurry I'll run full throttle at 8500' or 9500', 2500 RPM, mixture leaned for best power (about 14 gal/hr). But usually I'll climb to 9500 or 10500' or higher as needed, full throttle, 2300 RPM, mixture leaned to 10 to 30 F lean of peak, 9.9 gal/hr. (at the best power setting I'll see 172 KTAS; at the 10 gal/hr setting, 160 KTAS. Note 'funny' arithmetic: on trips between 600 - 800nm, the slower speed is "faster" as I can skip a fuel stop. We don't get air-to-air refueling!)
Descent: Just reduce throttle to keep speed under control. Enrichen the mixture as need to keep the engine warm (on my engine, I can lean until the engine produces no power, there is never any roughness).
Before landing, (below 5000'MSL), mixture rich, prop full forward, throttle as needed.
I cannot recommend enough adjusting your injector nozzles to allow LOP operation. It's easy and relatively inexpensive.
