Set up a single jump as an upright, practice jumping it on the diagonal to get you used to jumping on an angle.
Put a barrel or a cone 2 strides out and practice turning it at the barrel to the jump, turn this around and practice turning straight after the jump aswell, you can reduce this down aswell once you've got it cracked at 2 strides.
Start with these quite small if your pony isn't used to tighter turns etc so pony can sort their legs out. Good luck
