First thing is to torque BOTH cranks. That is usually what causes a creak.
Then check the pedals. Put a wrench on them. They can look and feel tight, and still creak. Check your cleats if using clipless.
Check all of the chainring bolts. One loose one can cause noise, especially under load.
Now the silly stuff. This happens a lot and can be hard to find.
Check your front der cable end. If it is sticking out to the side, it can be hitting your shoe. It can sound like a loose crank.
You could have a shoelace or shoe strap that is hitting the chainstay, seatstay or your cranks.
Your saddle can creak in rythm with pedaling. Some dirt on the rails or in the clamp can cause this.
On my MTB I had a creak when I pedaled that ended up being my front shocks. It almost drove me nuts. There was no way that it sounded like the shocks. Remember that bikes are made up of metal tubes, and that can really cause sound to travel around.
