How to insert and offset on movement in the direction of he object is facing?

Hi,

I'm making a game that the object is moved with one finger and can be rotated using two fingers.

For making the movement I simply using

     if (Input.touchCount > 0){
         theTouch = Input.GetTouch(0);
         if(theTouch.phase == TouchPhase.Moved){
             Vector2 clickPosition = Camera.main.ScreenToWorldPoint(theTouch.position);
             transform.position = clickPosition; 

But, the result is not great for me, because the object stays covered by the finger, so I wish to make a little offset, só the finger stays on unit in front of the direction of object.

I tried using

 Vector2 clickPosition2 = transform.InverseTransformPoint(clickPosition);

and setting the

 transform.localPosition = clickPosition2 + offsett;

but the object stays teleporting in different places on the screen (maybe because it it's making a circular reference?)

What should i Do?
