Point character at next waypoint

I'm using a pathfinding library to move my character. It's moving along the path great, but now I want to point the character at the next point to move to. I have a model and character controller. The code used to move the character controller (which works) is:

//Direction to the next waypoint

Vector3 dir = (path.vectorPath[currentWaypoint]-transform.position).normalized;

dir = speed Time.fixedDeltaTime; controller.SimpleMove (dir);

When the model is standing upright the rotation is 270,0,0. This is a purchased model so there must be some coord system issue and Unity must automatically fix that by rotating it 270 for me because I didn't do that. But how can I get my model to point to the direction my controller is moving but only on the Y axis?

Thanks!
