Try out teutons if you have the time and want to be off.
Just don't be too surprised when you get attacked 
Thanks for that suggestion.
What do you mean by "want to be off"?
If you want to be an attacker.
Teuton is a very good tribe, but is time demanding. You will get punished harder for your mistakes, but if you get good on them you will be a good asset for every alliance.
Each tribe have there strength and weakness, I would recommend you to take a look on travians tribe guide.
Martina is guiding you through each tribe.
As a gaul I would recommend to raid with TT, but if you wanna change tribe I would take teuton if you want to play offensive.
Hey Fire!
Its hard to answer your question because it doensnt clearly say how much time you want to spend on Travian, do you play to win or to have fun, how much gold pr. month. From what i can understand you seem fairly new, atleast as an offensive player.
The current farmlists are very easy to use and you can setup from 2-3 villages, it takes a couple of hours 1-2 days and then youre set up for a good period with nice free income, so you dont have to overdo it and burnout yourself, it is still recommended.
In regards to your race and if we are only thinking early game, the teuton race is really effective with hero and clubs, but as said before its risky if the enemy counters your clubs(sends horses back when your troops return). Gual would be easier because you can always build the trapper.
So spend 1 day making a farmlists, send it as often as you want. Play the tribe you prefer playing, usaully whats best for raiding are what you find the funniest/most worth spending time on because then you send more raids. Gl
