Is it always used in Present Continuous?

Answer

We don't say 'lack in': only 'lacking in'.

In the phrase 'she's lacking in manners', the word 'lacking' is a predicative adjective.  The collocation goes like this:
be + lacking[adj] + in + noun.

When we use the word 'lack' as a verb, it takes a direct object (no preposition):  'She lacks manners'.
