Using tener que, I changed the conjugation to match the the subject of my sentences:
1. Tengo que ponerme maquillaje.
Translation: I have to put on makeup.
2. Tenes que ponerte sapatos mas bonitos.
Translation: You have to put on more beautiful shoes.
3. Tengo preparar la salsa por todos.
Translation: I have to prepare salsa for everyone.
Hope this helps! Feel free to ask any questions.
