I'm attempting to apply a jumppad type effect to the character controller and I'm having some trouble getting the player to fly off in an arc. What would be the best way to do this?

If you're using the CharacterController or SphereCharacterController, they try to stick to the ground. Forcing a jump (or equivalently clearing the support data like a jump does) will unstick them, allowing an impulse to fully boost the character.
