How do you make cheap asian instant noodles without noodles?
Trying not to interpret this as a recipe request, but a question about how to approach recipe mimicry.

Look at the ingredient list of flavourings you like. Try and sort them by function: six basic tastes (umami/sweet/sour/bitter/salty/fat), aromatics (spices, alliums of any kind, and other vegetables and vegetable extracts), textural modifiers (eg starches, emulsifiers), and stuff you do not need in a fresh recipe (preservatives etc.). Develop a recipe from there. Pay attention to oil vs water vs alcohol solubility of aromatic compounds.

or/and/also

Look at what dishes the seasoning is based on (eg japanese ramen broth+tare combinations, thai curry, chinese soups) - then look at recipes for these dishes, optionally cook some of them from scratch (you will be working with about a half to three dozen flavour defining ingredients, and get to know all shelves at your asian grocer's), to get an understand for the seasoning profiles.

Also learn about stock making - bone broths etc. if you want it meat based. If vegetarian, experiment with shiitake/kombu dashi, and fermented ingredients like all the varieties of soy sauce (hint: you want some thai/chinese light 
 and/or gukganjang), gochujang, douchi, sufu, chinese pickles, kimchi....

BTW, you will arrive at a point where you make broths that are just too intense without noodles...
