Dry soup is "de la soupe instantanée", "de la soupe en sachet", "de la soupe en poudre". "de la soupe lyophilisée" is the exact term, but being too technical and hard to spell, the term is barely used.
la soupe (fem.), le potage (masc.), le velouté (masc.). "la soupe" is the vegetable one. "Le potage" and "le velouté" are nearly the same thing, but in a higher registry of language, or speaking of asparagus soup. You would use these (a bit showy) words on a restaurant menu.
