Teleport player facing the direction he previously faced

Hello. I'm currently making a Warping Sword where the player sneaks to create a warping point (area effect cloud). The player then teleports to that warp point if he attacks an entity. My problem is that I always face south when I teleport.
How do I make it so that I tp to the effect cloud while also facing the direction I was facing before the teleportation?
Thanks guys!
