-았/었/였으면 좋겠다 is the grammatical structure that expresses a wish or a hope, and just like when the English verb 'to wish' is used, the conjugated structure of the verb in Korean is also usually in the past tense. The form in the present tense, -(으)면 좋겠다 can also be used, but the past tense is more commonly used, especially with the ending part "좋겠다".

* When the first part of the sentence is expressed in the present tense (으)면 instead of the past tense, the ending part, 좋을 것 같아요 can go along with it most naturally.
Examples:
* 내일 비가 안 왔으면 좋겠어요.
* 빨리 내 생일이 돌아왔으면 좋겠어요. (돌아오다) I wish my birthday came around soon.
* 니가 담배 끊었으면 좋겠어. (끊다) I wish you would quit smoking.
* 내 생각이 틀렸으면 좋겠다. (틀리다) I wish I was wrong.
* 꿈이었으면 좋겠다. (이다) I wish I was dreaming.
