orthogonal mirror is very simple
say you want mirror parallel to XY plane, that's one of general 2 solutions I know (without stencil buffer):
1. draw everything with inversed Z coordinate, thus if your whole mirror has all Z coordinates = some_z you need to replace z coordinate of your objects with
(-z + 2*some_z)
2. clean z-buffer
3. draw alpha-blended poly over the mirror
4. draw everything
hope it helps

There is a very good tutorial about mirrors (Using the stencil buffer).
