Common adjectives that describe smoke are 'dichter' (thick), 'schwarzer' (black), or 'weißer' (white) smoke. A typical verb is 'aufsteigen' (to rise): smoke rises from the fire.

'Schall und Rauch' (sound and smoke) is a fixed expression that is often used with 'sein' (to be) or 'sich erweisen als' (to prove to be). It describes something that turns out to be meaningless, empty, or fleeting, for example empty promises.
Seine Ankündigungen waren am Ende nur Schall und Rauch.
In the end, his announcements were nothing but sound and smoke.
