Replacing the masala with a homemade mix is an option. Spices that could potentially replace cumin powder, turmeric powder, coriander powder, and red chili powder.  Garam masala is another option for a warm flavor; it contains cloves, cinnamon, cardamom, and black pepper.  Another way to make your dish taste similar to Maggi Masala is by adding some tomatoes, ginger, and garlic to the recipe.  Try soy sauce or fish sauce instead if you're asking for a savory flavor.
