Tree Nature Shader

Well my plans when I was developing the Design of my Game was to make some trees had glowing leaves (alien trees), so I modeled the tree and at first Transparent Unlit seemed good, but the problem was that unlit was one-faced only,then the Nature\Tree Soft Occlusion leaves had it's good side because were two-faced, but it does not fit in the glowing stuff. How can I make an Unlit Nature Leave Shader, or a Two-faced Unlit?

Thanks, FGP.
