How do you say let's?
As in: Let's go to the mall. Or let's do somthing. Would you just put vamos?
They call these nosotros commands (or exhortations).
There are several ways to make them.
- you use the 1st person, plural, subjunctive form of the verb
- you use a phrase including vamos+a+verb infinitive
- you use a phrase employing que and the subjunctive verb

So as far as I know, the best equivalent for let's is vamos, as jeezle said. Let's is really an expression that doesn't really make sense if you think about it (let us? what?) so unless there's a better translation that is more similar to the original contraction, stick to vamos.
Yes. To say let's you just conjugate the verb. Let's go = vamos.
