Hi,
I always go through a pre take-off brief, in a single as well as twin. The twin is a little more involved though.
For a piston twin I would use the following.
-----
This will be a normal / crosswind take off from Runway Three Zero. The crosswind component is ten knots which is within the seventeen knot demonstrated crosswind limit. Flaps will remain fully up.
Rotate speed will be 75 knots. Climb at 88 knots. Gear Up when insufficient runway remains. 500' AGL (convert to QNH altitude) Manifold 25", RPM 2500. At 1500' AGL (again convert to QNH altitude) increase speed to a cruise climb of 105 knots.
If we have an engine failure, fire or loss of directional control during the take off roll, throttles immediately closed, maintain directional control and stop using the remainder of the runway.
If an engine failure or fire should occur after rotation with sufficient runway available to land back on, throttles immediately closed, maintain directional control and land back onto the runway.
If an engine failure or fire should occur after rotation and below 300' AGL (convert to QNH altitude) then throttles immediately closed, maintain directional control, ensure gear is down and use flaps as necessary to land in a field within 30 to 40 degrees of the nose.
If an engine failure or fire should occur at any other time, ensure mixtures are rich, props fully fine, throttles fully forward, flaps up and gear up. Climb at 88 knots blue line speed Vyse. Verify and Feather. Proceed through the engine secure checks. Declare an emergency and land as soon as is possible.

Hope this helps.
Best wishes,
