Okay, so reduced-size but WITH numberpad? Let's see...
-Quickfire TK, as mentioned.
-Plum 96: similar to QFTK. Comes with MX Black by default, which may be good for you, but is also PCB-mount, so easy to change.
-Tt MEKA (with no G or anything): same width as the above, but has arrow keys tucked underneath Enter, so you can use them and the number pad at the same time. Once again MX Black.
-Cherry G80-1865: Has all the keys of a full-size (I think), but kinda squished together to make it narrower.
This is off the top of my head...there might be more out there that can be found with some digging.
