I make routines with people that are most important to me (and open to it). Like one friend I see every Tuesday afternoon. 3 friends and I have a weekly Zoom call (we frequently change the time but the baseline is that it is once a week). For people harder to do that with, I kind of just text them when I remember they exist or if they texted me- this means I can go months or years without texting them though
As for content- I find when talking we get to interesting enough topics and if we don’t we just sit and nod and enjoy the company. If texting- text them something that you think they may find interesting or funny. Like something about your day or interests or something you overheard or read or watched
