Best advice is bring it to a mechanic and let them figure it out.
Or if you're determined to do it yourself it'll be a pain but here's what you have to do.
Step 1 go to the broken plug and punch the electrode and the porcelain that surrounds it into the cylinder (well come back for this later)
step 2 use a screw extractor preferably a irwin spiral screw extractor, and carefully tap it into the threaded portion of the broken spark plug and try reversing it out. If it doesn't move don't keep trying to turn the extractor you'll be in far worse shape if you break that in there!! If it isn't moving you'll have to try and get some heat on the threads with a torch but be careful. Then try the extractor again with the same method and it should work.
Step 3 inspect threads for damage, repair if needed.
Step 4 grab a magnet and fish the electrode out of the cylinder, and whatever bigger pieces of porcelain you can get.
Step 5 start the engine just for a couple seconds and the left over pieces of porcelain will fly out the spark plug hole.
Step 6 put in new plug and realize you spent way to much time trying to get this plug out but feel like a bad ass car wizard for doing it yourself!!
