Notes
ように (前に言ったように "as I said before") is always the resemblance よう, but
non-past can be that よう too (思うように "as I'd like") — the disambiguator is the
clause relation to what follows, not tense alone.

ように is the default for outcomes the subject cannot will directly — potentials, states, and most negatives (間[ま]に合[あ]うように急[いそ]ぐ, 忘[わす]れないように書[か]く); negative ために is still productive where the avoided outcome IS controllable (失敗[しっぱい]しないために練習[れんしゅう]する — failing is something effort can prevent). ように is also required whenever the goal-clause's agent differs from the main clause's subject (子供[こども]が食[た]べるように、細[こま]かく刻[きざ]んだ "cut it up small so the CHILD would eat it") — ために needs one shared subject across both clauses and cannot switch agents at all.
Lookalikes
Same ように string, different grammar — ようになる is a fixed idiom marking a gradual change (話[はな]せるようになった), while purpose ように is a free clause connector that can precede any main verb naming a deliberate action (電車[でんしゃ]に間[ま]に合[あ]うように急[いそ]いだ); if the word right after ように isn't なる, this is the purpose connector, not the change-of-state idiom.
Same ように string again — ようにする anchors a standing habitual effort with する itself as the main predicate (毎朝[まいあさ]走[はし]るようにしている), while purpose ように is subordinate to a DIFFERENT main verb naming the concrete action taken to reach the goal (急[いそ]いで書[か]いた, not ように書いた alone); ようにする's ように never stands directly before any verb but する／している／した.
Both can gloss as "in the way that," but とおりに demands a concrete PRIOR reference being reproduced exactly (先生[せんせい]が言[い]ったとおりに書[か]いた "wrote exactly as the teacher said"), while ように names an approximate goal with no prior utterance required (聞[き]こえるように話[はな]す "speak so as to be heard") — とおりに freely takes a past-tense verb before it, but purpose-ように never follows a past clause (×聞[き]こえたように話[はな]す is odd).
