yoshikoさん、こんにちは。ご質問ありがとうございます。
一例をご紹介させてください。
《英訳例》
Are you eating at home tonight?
今夜は家で食べるの。
↓
eat at home
家で食事をする
tonight
今夜は
《語句》
【英辞郎】
eat
【自動】食事をする［取る］、ご飯を食べる
at home
自宅［自分の家］に［で］、在宅して
《解説》
★ 英訳例
直訳は「今夜は家で食べるの」です。この言い方のほうが簡単かなと思いました。
★ be doing
「現在進行形」は「今…している」という意味でよく使われますね。これ以外に「確定的な予定」を表すこともできます。
【グリーンライトハウス英和辞典】
be【助動】［be＋現在分詞で進行形を表す］
(もうすぐ)…するはずだ, (近く)…するつもりだ《未来を表す副詞(句)を伴って近い将来の予定を表す》
《例文》

Should I prepare a meal for you this evening, or not?
Your wayward daughter is a little unpredictable these days as she quite often dines with her friends in the town or at someone's home. You are never sure how much food to cook for your family!
"Are you eating at home or eating out tonight?"
"I'm out tonight, thanks."
Or, a slightly more indirect way of asking is:
"Should I prepare a meal for you this evening, or not?"
"What are you making?"
"Shepherd's pie."
"That's my favourite! OK, I'll eat with you tonight!"
例
わがまま娘の行動がちょっと予測不能になってきた。彼女は最近街で誰かと一緒に食事をしては、誰かの家に泊まっているみたいだ。家で何人分の食事を作ればいいかさえわからなくなってきた。
"Are you eating at home or eating out tonight?"
"I'm out tonight, thanks."
（今日は出かけるから大丈夫、ありがとう。）
または少し間接的に尋ねる方法としては以下。
"Should I prepare a meal for you this evening, or not?"
今夜の食事を用意しますか？しませんか？
"What are you making?"
何を作るんですか？
"Shepherd's pie."
シェパードパイです。
"That's my favourite! OK, I'll eat with you tonight!"
ああそれは好物です。わかりました。今日は一緒に食べます。
Are you coming home for dinner or are you eating out?
Will you be home in time for dinner?
Are you planning on eating dinner at home?
In the first sentence you will see the term eat out. This means we get our food at a restaurant or cafeteria instead of eating at home. In the second sentence you will see the term in time, which means not late. These two terms would be great additions to your vocabulary.
You can ask your daughter "are you eating at home tonight?"
Other variations on how to enquire whether your daughter will be joining you for dinner include:
"Will you be eating in this evening?"
"Are you having dinner with me at home tonight?"
"Will you be joining us for tea tonight?"
Are you eating at home tonight?（今夜、家でご飯食べる？）と娘に聞くことができます。
あなたの娘が夕食を一緒に食べるか聞くには、他にもあります。
Will you be eating in this evening?
今夜、夕食は食べるの？
Are you having dinner with me at home tonight?
今夜、一緒に家で夕食を食べるの？
Will you be joining us for tea tonight?
今夜、一緒にお茶でも飲む？
We can talk about, "eating out," or, "eating at home," to describe the two possibilities. We can also simply ask if they are going to eat at home without mentioning the opposite. Lastly we can talk about, "making it home," to express/ask if they are going to come to home for dinner as well.
