In a small bowl combine 1/2 cup of yogurt and chives; refrigerate until ready to serve. In large stock pot, place potatoes with enough water to cover. Cook until tender (15-17 minutes) and drain. In a large saucepan, bring 2 cups water, salt, soy sauce, mushrooms and shallots to a boil. Reduce heat and simmer until 1 cup of liquid remains (about 25 minutes). Remove mushrooms and shallots from liquid reserve and set liquid aside.
Place mushrooms, shallots and cooked potatoes in blender or food processor and blend on low until finely chopped, add reserved liquid mixture, milk and remaining yogurt. Blend until smooth. Return mixture to saucepan and heat slowly. Ladle into bowls and garnish with yogurt and chives.
