You should still be able to fly by looking out the window, and using standby altimeter and airspeed indicator. If you're lucky and happen to be in an aircraft fitted with ISFD, that has its own battery that should last 150 minutes, so you get the artificial horizon as well in that case. Magnetic compass obviously works, but it may be a bit off, since it's normally calibrated with all the electrical equipment switched on.
Flight controls should work normally as you have both EDPs operating (otherwise it's back to manual reversion), but you lose the ability to extend flaps. Emergency landing gear extension should work as well. No reversers on landing, but normal brakes and nosewheel steering should still work.
Not sure if you'd be able to shut down the engines as all valves are electrically actuated, but if you've made it that far, that's the least of your problems
