First of all you should create an LVM that is at least the same size of the original one. Then you can do something like:
local# dd if=/dev/vglocal/lvm-old | ssh remote dd of=/dev/vgremote/lvm-new
And that should do it. If you already have a file with the original lvm on the remote server, then something very similar can be done:
remote# dd if=/path/to/img of=/dev/vgremote/lvm-new
You could also add the option bs to increment the blocksize used by dd, to speed up the process:
# dd if=... of=... bs=131072
