Need help with wall jumping at an angle

I’m trying to set up wall jumping for a 3d project. Essentially it does a line trace by channel to scan if the model is against a wall. Then jumping will launch the character away from it. The issue I have is that every wall jump sends the character back the way it came because the vector is hard coded and I don’t know how to get a variable for it. I found out about reflection vectors but I can’t find much in the way of how to use them. I’d like to set this so that the jump angles off the wall like a V. For instance, if I jump into a wall at a 20 degree angle, the jump away from it would be at 160 degrees.
