With reference to MinnFlyer's drawing and to be slightly technical. The wing generates an amount of lift ALWAYS perpendicular to the wing surface. This would be shown as arrow B. In level flight all it is doing is holding the plane up. Once you bank (roll) the plane most of the lift continues to support the plane but some of it pulls the plane in the direction of the roll (arrow C). The further you bank the plane the more supporting lift you will lose. Since you have lost a portion of the supporting lift you need to now apply a small (for shallow rolls) amount of elevator to compensate or you will get motion in the direction of arrow A. As you return to level flight you will decrease the elevator input. The amount of elevator input will depend upon a great number of things such as a/c type, wing shape/type, speed, amount of bank and others. This is one of the many things your instructor will help you with. The horizontal stab usually pushes down in flight to keep the plane in balance but that is another subject entirely. There may be some theorists out there that may argue my exactness but I am substantially correct.
