You really need context to get a real answer here. First, you need to specify who is doing the wanting. Spanish has six different present tense forms, while English has only two. For example, the English is "I want, you want, he/she/it wants, we want, they want." In Spanish, this is "yo quiero, tú quieres, él/ella/usted quiere, nosotros queremos, vosotros queráis, ellos/ellas quieren."
Once you know who is doing the wanting, then you can add the secondary verb, as in "I want to run", "Yo quiero correr".
Finally, in Spanish it is not necessary to use the personal pronouns, unless you need clarification or emphasis. In the above example, "quiero" can only be used in the first person, so the "yo" does not need to be said. "Quiero correr" would be more normal.
To say 'I want a chair' in Spanish, you would say 'Quiero una silla.'

querer- to want
I want = Quiero
"What do you want to do?" Say "Que quieres hacer?"
