Quaternion help with top down camera

I have my camera set to follow directly overhead from the player. I need the camera to look directly at the player but I also want it to rotate so the player is always facing the top of the screen. The kicker is I need this to work on a planet-like environment.

Here's what I have:

 Vector3 origin = FollowTarget.position + FollowTarget.TransformDirection(FollowOffset);
     Vector3 position =  origin + FollowTarget.up * _height;
     transform.position = position;
      Quaternion rotation = Quaternion.LookRotation(origin - position);
     transform.rotation = rotation;
 

With this the camera looks at the player target but does not rotate with the player's direction.
