'Let's have a drink' - Tomemos una copa
Vamos a tener.
nomas
Vamos a trabajar.
there is not an exact translation for it; it depends on what you want to say. ex: lets go eat - vamos a comer lets jump- saltemos ( as you can see in this case there is no word used instead of lets, but it is understood as lets jump)
