Heat the oil in a large saucepan over medium heat. Add the onion, carrot, and potato. Cover and cook for 4 minutes to soften. Stir in the celery salt, broth, corn, and salt and pepper to taste. Bring to a boil, then reduce the heat to a simmer, stir in the coriander, liquid smoke, and almond milk, and cook, stirring frequently, for 5 minutes.
