What I do is I stand still, wait for one of them to get close with Snake.
Tap A, and don't hold a direction- this knocks them a good distance away and does great damage.
Or, alternatively, side smash A and then follow up with Up + A in mid air. The side smash knocks them to the side, of course, so following up may be somewhat difficult, but they get some stun on this, and his Up + A aerial gives some pretty insane knock back in a very vertical direction.
And if you REALLY want to be cheap, spam his up smash. You hit a little bit of the space in front of you, knock anything in range upwards, and then you have the mortar round drop back down for secondary explosive damage, which gives more of the knockback you've come to expect from him. Pretty quick, too.
That's all I can think of off the top of my head without actually having a working Wii console right now.
