★verb (ta-form) +あとで(ato de)★
あとで (ato de)means “after doing”.  To express that something happens after something else, we should use the past (ta-form) of a verb followed by あとで (ato de).  

昼ごはんの後で友達とお茶を飲みました。
I drank tea with my friends after having lunch.
Hirugohan no ato de tomodachi to ocha o nomimashita.

授業の後で映画に行きませんか？
Won’t you go to the movies with me after class is over?
jugyou no ato de eiga ni ikimasen ka.

薬を飲んだ後で、一時間寝ました。
I slept for about an hour after taking the medicine.
Kusuri o nonda ato de, ichijikan nemashita.

私は宿題をした後でテレビを見ます。
Watashi wa shukudai o shita ato de terebi o mimasu.
After doing my homework, I’ll watch TV

子供が寝た後で、映画を見みました
kodomo ga neta ato ni, eiga o mimashita
I watched a movie right after my child went to bed.

たあとで also have the nuance of emphasising the fact that action B takes place after A (and not before). It’s good to remember that this grammar point uses the た form, which is the past tense in plain form.

ほんをよんだあとで、ねました　
hon wo yonda atode, nemashita.
I went to bed after reading a book (but between reading and going to bed I did other things, eg. brushed my teeth)

てから is used when the second action (B) is going to happen straight after the first (A). In a lot of A てから B sentences, action B is only possible after completing action A. For that reason, it is useful when you want to express actions that take place in a specific order, such as in your daily routine.

ほんをよんでから、ねました
hon o yonde kara nemashita
I went to bed after reading a book
