Everything you need is here at Touch.

In your current code all you need to do is Instead of Input.mousePosition you use Touch.position.

So it is like, instead of:

Vector3 mouseWorldPoint = Camera.main.ScreenToWorldPoint(Input.mousePosition);

it becomes:

Vector3 mouseWorldPoint = Camera.main.ScreenToWorldPoint(touch.position);

Also you can handle touch being moved on screen using TouchPhase.Moved.
