Shaykh Maher (imam of Harem Makkah) gives some very practical advice here:

He says:

Ideas for the last ten days:

1. Give 1 dinar in charity every night, so if it falls on laylatul qadr it's as if u gave charity everyday for 84 years.

2. Pray two ra'kaat every night, so if it falls on laylatul qadr it's as if u prayed everyday for 84 years.

3. Read Surah ikhlaas three times a night, so if it falls on laylatul qadr it's as if u read the whole Quran everyday for 84 years.

He then says spread this as you may find it on your account [of good deeds].

Allah make us of the victorious.
