Correct the yaw with some gentle rudder input, the aileron is supposed to be used for track corrections once you are airborne. The aileron inputs should be kept as little as possible to avoid any spoiler deflection on the wings.
In the air, normal control laws of the Airbus counteract automatically any deviations in bank.
Good luck man
Agree, great information, learn how to slide your hand down to the rudder trim without looking, turn in the direction of the good engine for approximately 10 seconds, a nice slow rotation when you see the engine fail will help.
