Which Hindi verb forms are fully conjugated?

In the Hindi language, only the present and future indicative forms are fully conjugated.

Other tenses in Hindi are not fully conjugated in the same manner; instead, they are formed by combining perfective and imperfective participles with auxiliary verbs. For example, in the sentence ādmī laṛkī-ko dekhtā ("the man sees the girl"), the verb dekhtā ("sees") is etymologically a participle that agrees in number and gender with the subject.12
