One thing and one thing only causes an aircraft/aerofoil to stall: increasing the angle of attack beyond the critical.
Recovery is effected by reducing the angle of attack below the critical.
This is normally done using the elevators.
Adding power as you move the elevators down will help the wing unstall more quickly.
Once the aerofoil (wing) is unstalled you can use the flight controls normally - rolling wings level and raising the nose at this point will prevent further height loss.
Not much else is important.
