In short terms, you need to sniff the 4-way handshake between a legitimate client and the AP it connects to. This can sometimes be forced by spoofing a "deauth" (disconnect) packet from the client, but requires support in the chipset for your wlan-card. (Injection and monitor mode).
Once you have the handshake, your options are either aircrack-ng, hashcat or other password cracking tools. Some of these have a crazy amount of options and possibilities for cracking, and getting to know them can increase your success rate by a lot.
However, the easiest way these days is to exploit WPS in the AP. Look up Reaver and Pixiewps.
