trying to change a bathroom vanity and the water doesn't have a shutoff valve. what do i need to do?
turn off the water to the house (main valve).
turn off hot water.
remove old vanity and put on shutoff valve? does it glue on?

That is some cheesy ass plumbing you have going on there.

turn off the water, try the sink to make sure its off, remove fittings, install shut off valve, (screws on), install new vanity (use teflon tape on all fittings) turn water back on. It should not be hard.

For the love of all that is goodness...add a shutoff valve and run some braided lines to the faucets/toilet.

Are the supply lines copper at least?

turn off hot water.

Not to be rude, but let's think about this one for a second. :hmm:

Hot water pressure is still coming from your main water source, be it city or well pump. Hot water is pressurized from the main water supply, unless your city is providing you with hot water, and in that case I want to go to there.

You only need to turn off the main but make sure to turn on the faucet where you are working after you shut it off to get rid of the line pressure, and keep a bucket handy for the little bit of extra water in the hose. When you turn the main water back on, do it slowly (don't want anything to burst) and leave that faucet open so you can get any air in the line out.

EDIT: My second paragraph makes little sense when I read it, lol.

Turn off main.
Open faucet that you are working on to let any residual pressure/water out.
Put bucket under work area and remove hose.
Replace fixture and reattach hoses. (Add valve if you want.)
Leave faucet turned on.
Turn main back on, but do it slowly.
Turn off new faucet after air is out of system.
Profit.

That piping looks to be PEX or PB. While you could add a shutoff to the lines, you do not really need to. If i were you, I'd just replace the vanity/sink without any piping modification.

Is the whole house run with that same piping?
