Well, you could export the file system content using services like NFS
or Samba, but it sounds like you're after exporting actual block
devices, in which case you'll need to consider something like iSCSI, nbd
(or gnbd) or some other network block device type.
This is all assuming that your lvm volumes are on local storage (e.g.
SATA, IDE, single initiator SCSI/SAS) - if they're on shared storage
like a SAN you should just be able to present them to the backup host
via the storage network.
