I do my fishing and cooking dailies (which takes about 10 minutes to do for me) as well as my daily rare->epic gem transmute which I sell on the AH. That makes me about 200g.
Also, I fish up glacial salmon and pygmy suckerfish. The salmon sells for about 50g a stack and takes less than 10 minutes to get a stack. I use the suckerfish to make guru's elixir which sells at 60g a stack. Combining both of them makes for about 160g for every 15 minutes of fishing.
Another good place to fish is wintergrasp. The fish you get there is glacial salmon, nettlefish and musselback sculpin, all used for fish feasts. And you can use the spices from your cooking daily, (or exchange cooking badges for them). The fish feasts sell for about 10g each.
The only thing about making gold is that you have to dedicate time to it. You can't expect to make lots of gold just by doing things casually. I managed to get the 3k gold needed for all of the kirin tor ring upgrades in less than a week.
