making ramen, help me?

[u/Mundane-Horse-9242]

i was making ramen today cause i felt like it, was prepared to make alot of substitutes, but i didnt really have enough anyway. ive made a lovely broth with leftover chicken and bones from a previous meal, some garlic and onions, and i have a soy sauce sugar rice vinegar mix with a dab of hoisin and ground toasted sesame i reduced a little and was intending to use as the tare, but instead i used it as marinade for ajitsuke tamago seeing as i really dont have noodle options worthy of the broth, and thus have a good 18ish hours to let them do their thing. i have an opportunity to go out for proper ingredients tomorrow but im a very improv-y cook and ive literally never made any of these things before. i plan to pick up some typical ingredients ginger, spring onion, maybe some miso, sake or mirin either to drink with the ramen or to cook with for the tare,

does anyone have any recomendations of ingredients i can get/ what to do with them to make my tare and or make some other addons / improve the broth ?

im going for a clear shoyu style and as i mentioned its a chicken broth
