Read the Global Platform specifications for xAuth. I recommend getting the GP 2.1 specification because it's easier to read. The section you want to focus on is the Secure Channel 01 protocol. Delete, xAuth, initUpdate, etc. are all there.
Also contact Gem+. They perform the derivation data step of the Secure Channel 01, differently than the specifications. Since I've vowed not to use Gem+ cards, because of that proprietary step, I have would have to dig to find the document and I can't remember off top of my head.
