Can a gas water heater be shut down if the water tank is off?
Considering you wont be using the water, and it will only be off for a short time there is no risk at all. You can also shut off the cold feed valve to ensure water isnt siphoned out of the tank if cold water is used with the tank off.
What happens if there is no water in the tank?
In most circumstances, there will be no water use for days, maybe even weeks and this doesn’t cause any problems with the tank. Even if someone does use water from the tank most (if not all) modern water heaters have low water cutoffs normally built into the unitroll (or aquastat).

Is it safe to turn gas back on after turning it off?
Once every appliance in your home has been turned off, you are safe to turn the gas back on. Find the safety shut-off valve that you used to turn the gas off in the first place. It could be anywhere in the main gas line. If the valve is perpendicular to the main gas line it should be shut, and if it’s in line with the pipe then it should be open.
