You don't.  Don't put partition tables on LVs.  The whole point of using LVM
is you don't need to partition anymore, and your block devices can be dynamic.
If you another block devices, you lvcreate it.  If you don't have enough space
in your VG, you add a PV to it, then lvcreate the new block device.  Have you
read through the HOWTO referenced below?
