There is a chapter in Programming in Lua that covers this kind of stuff, I suggest you start by reading that.

Essentially, maintain a separate Lua state for each AI, and store the pointer to the c++ object in the registry under a specific known key (I use uuidgen for keys) then implement some plain C functions which retrieve the this pointer and forward the call to the C++ object with converted parameters (so you're not passing the Lua stack around) if necessary.

Thanks,
