Well, if it’s one to one then you can start simple by getting to know each other, talk about family, pets etc. basic stuff
What do you have for textbook/resources?
Picture books with lots of nouns and text that you can point to, say words & get them repeat are a dead simple way to quickly increase vocabulary as nouns are easy to file away in memory
If the person you’re teaching is at a slightly more advanced level I 100% recommend reading a play with them. Any two-person drama where you each take a role is a great way to practice reading, speaking and listening all at once & can be really fun
Other suggestions for one-to-one, especially this time of year is to do walk-and-talks. Get out of the classroom and let the environment you’re in spontaneously steer conversation. This is also an excellent way to memorise things and talk in comparatives: over/under, near/far, big/small etc. It will also make a refugee feel more comfortable in their new environment to be able to talk about the things around them, and a lot of their learning will be in observing how you communicate in that environment. It’s quite often small contact things that make an unfamiliar person feel awkward in a new country - ordering a coffee or an item in a shop without being embarrased, understanding words for numbers/money & change …that kind of thing
So go get a coffee or whatever and maybe make it a regular thing to try a different sandwich or pastry each week or something like that
