Change Angle of Top Down Camera

I have a scene set up with a cube that has some basic 8 directional movement. The camera I have is for top down use, but I would like it to be angled closer to 45 degrees rather than 90 and still center on the character. Currently when I do this the camera literally centers on the character and looks away from him. When I attempt the LookAt function the camera turns with the character which is undesirable. Any Ideas on how to fix my code / any tutorials that will help me understand camera functions better specifically involving vector3's.

Here's the code:

 using UnityEngine;
 using System.Collections;
 
 public class TopDownCam : MonoBehaviour
 {
     public float dampening = 1;
     public GameObject target;
     Vector3 offset;
     
     void Start()
     {
         offset = transform.position - target.transform.position;
     }
     
     void LateUpdate()
     {
         Vector3 endPos = target.transform.position + offset;
         Vector3 position = Vector3.Lerp (transform.position, endPos, Time.deltaTime * dampening);
         transform.position = position;
 
     }
     
 }
