If engine fails after Vr (without available runway):

CHOP (the power), DROP (the nose to approach speed), SHUT DOWN the engine (Mixture—OFF, Fuel Selector—OFF, Ignition—OFF, Flaps—AS NEEDED, Master Switch—OFF), LAND STRAIGHT AHEAD (or slightly to the right or left to avoid obstacles)

Before taking off from an unfamiliar airport, check the surrounding area using Google Earth to determine potential landing areas if you can't turn back. Also, know your Minimum Turn Back Altitude. To determine this altitude for your aircraft, use the following procedure: 1. Climb to 3000 ft. AGL. 2. Cut the power and wait for 5 seconds (to simulate real-life lag time in recognizing the problem). 3. Pitch for best glide and roll into a 45° bank. 4. Roll out of the turn after 360° (to simulate the actual amount of time required to make a full turn back to the runway), then arrest the descent with a simulated flare. 5. Add another 50% of the altitude lost to the total (for a margin of safety) to determine the total turn back height. When turning back to the airport in an actual emergency, be sure to make the turn into the wind (this will result in a smaller turn radius and less altitude lost). Use a 45-degree bank angle (higher bank angles result in less altitude lost because of less time in the turn; however, steep bank angles drastically increase stall speed, so keep the nose down). Coordinate the turn and fly at the best glide speed. Feather the prop. Focus on performing the maneuver correctly rather that on attempting to restart the engine.
