Fly the recommended turbulence penetration speed. If the AOM doesn't give you one, fly Va, the manoeuvreing speed limit.
Establish a pitch attitude and power setting that averages the desired altitude and airspeed. Allow the altitude and speed to vary in the gusts within safe limits. Intervene to control altitude and speed only when the variations become excessive.
Don't fight the aircraft, make your control and power changes smooth and positively, but NOT aggressively. Roll with the punches, again within safe limits, intervening only if the Altitude or Speed variation is excessive. (Lady pilots fly aircraft far better in turbulence in my experience, they're less prone to aggresively fight the aircraft).
If you're in controlled airspace, advise ATC of your speed and altitude variations, they may deem it necessary to provide greater separation with other aircraft.
Relax! The aircraft can take quite a pounding well beyond what you consider comfortable without any structural problems.
