I had a broken earphone (most likely drivers kaput) so I was thinking of turning it into a 2 pin wire for my Kz earphones with 2 pin connectors.

However erm... I have no idea how to solder ... as in which to which wire... is there a tutorial for it? Thanks.

General soldering tutorial can be found all over Youtube. You will need some practicing as 2 pins isn't the easiest thing to solder for beginner. You will need a soldering iron as well as some solder. Flux will help a lot.

For polarity on 2 pins, generally the ground pin is the one closer to your face and the hot / signal pin is the one closer to your back. However, some IEM has this on reverse, such as QDC.
