I'd recommend working on hand signals now if you don't already use them since she does have some hearing left. Waving back for "come" is really handy. If you need to wake her up, place your hand under her nose so that she can sense your presence and waken naturally...don't nudge her awake.
Good luck. When our Akita lost her hearing, we already had some hand signals. We used to send Honey to find Kiku out in the yard to "call" her for dinner.
